Function opencv::core::divide

source · 
pub fn divide(
    scale: f64,
    src2: &dyn ToInputArray,
    dst: &mut dyn ToOutputArray,
    dtype: i32
) -> Result<()>
Expand description

Performs per-element division of two arrays or a scalar by an array.

The function cv::divide divides one array by another: block formula or a scalar by an array when there is no src1 : block formula

Different channels of multi-channel arrays are processed independently.

For integer types when src2(I) is zero, dst(I) will also be zero.

Note: In case of floating point data there is no special defined behavior for zero src2(I) values. Regular floating-point division is used. Expect correct IEEE-754 behaviour for floating-point data (with NaN, Inf result values).

Note: Saturation is not applied when the output array has the depth CV_32S. You may even get result of an incorrect sign in the case of overflow.

Parameters

  • src1: first input array.
  • src2: second input array of the same size and type as src1.
  • scale: scalar factor.
  • dst: output array of the same size and type as src2.
  • dtype: optional depth of the output array; if -1, dst will have depth src2.depth(), but in case of an array-by-array division, you can only pass -1 when src1.depth()==src2.depth().
